Looking in to the potential market ACL has committed to contribute to enhance the cement capacity in the State of Karnataka while protecting environment of the region.

2.4 Need for the project and its importance to the country and region

Industrialization is the better way for growth & employment & also it is a strategic location connecting Indian markets. The industrialization and infrastructure growth have to go hand in hand. Cement is major component in infrastructure growth. Total Cement production in the area and nearby state does not match the demand growth and hence new capacities have to come up concurrently. The proposed plant will ensure that the supply situation in Karnataka is comfortable in the coming times, as growth is expected to propel demand.

Adani group is known for its environment friendly initiatives across sectors it operates in and strong reputation for sustainable growth. In line with the existing agenda to make India Power sufficient in the future sustainably cement manufacturing unit are being planned close to coal based thermal power plants the group operates. Disposal of fly ash is an environmental concern which is faced all coal based thermal power generating plants. Cement grinding can consume up to thirty five percent of fly ash produced in the power plants and thus reduce environmental concern.

The cement projects planned by group would also generate immense employment opportunities and significant contribution to the state & central exchequer., improvement of socio economics of the area by way of education, vocational training, animal husbandry, improving infrastructure facilities such as roads, transport, improvement in drinking water supply, medical facility etc. The Adani Group is committed to the development of the country and will put all efforts for comprehensive development of this area also as being practiced by us at other establishments.

2.4.1 Future Demand & Domestic / export Markets

The total market size of Karnataka, Kerala and Goa is estimated at approximately 18 million tons being catered from Gulbarga and Yeraguntla-Nalgonda clusters. The key players operating in this region are ACC, Ultratech, Orient, Bharti, Dalmia and others. The demand in these markets is expected to growth at par with the GDP growth rate (~7.5%) of the country.

Optimized logistics have been a key challenge for the players in this region and low cost logistics both in term of inbound for raw material and distribution cost will be the key success factor in this region. Leveraging on the existing railway infrastructure and utilization of low cost sea logistics is expected yield greater advantage.

Compressed air supply

Compressors and blowers have been -envisaged for operation of process equipment. The compressed air is also used for various bag filters installed to minimise air pollution and diverting gates, valves, blasters etc. Blowers are mainly used for aeration of silos.

Central Control Room (CCR)

A CCR building is envisaged to be constructed at site. This building can be located above the MCC room near cement mill section. Operation of the cement mill & Packing Plant will be carried out from this control room.

Manpower Availability

Since, there are many industries operating in this belt and therefore the required skilled manpower can be sourced easily.

8.0 HUMAN RESOURCES

8.1 Introduction

The Human requirements have been separately provided for the following two phases:

Project implementation phase. Plant operation phase.

8.2 Basic

The details recommendation for each phase has been taken into consideration the following: Project technical concept. Smooth and efficient plant operation, Effective inter-departmental co-ordination. Optimum organization with well-defined job responsibility. Optimum utilization of different levels of workmen and supervisory staff. Training needs of the personnel, wherever required, will be taken care of by UTCL.

Manpower requirement in certain categories like fitters, welders, khalasis, helpers, peons, canteen staff, guest house attendants, etc. can be met through contractor(s). Certain activities may be assigned to specialized agencies/ contractors. These may include loading-unloading, plant cleaning job, packing, and security for plant.

8.3 Project Implementation Phase

For the project implementation phase, the required resources will be sourced from concerned executing contractors.

8.4 Plant Operation Phase

For the plant operations the required resources will be sourced from concerned contractors or by our group units, further locals manpower will be utilized as per the skills.

8.5 Employment Generation (Direct and Indirect) due to the project

Direct and indirect employment will be generated due to the project. The total manpower requirement for the project is estimated as approx. 65 (Direct) and approximately 500 (Indirect). Unskilled/ semi-skilled manpower can be sourced from the local area and skilled manpower shall have to be sourced from outside/ local.

9.0 Planning & Implementation Schedule

9.1 Planning Schedule (Pre Project Activities)

9.2 Implementation Schedule (Project Activities)

The implementation period has suggested 18 months for project execution activities after placement of main machinery order until the plant commissioning. As per the project implementation schedule the expected implementation time has been estimated as:

Pre project activities: 6 months Project execution activities: 18 months

The schedule will serve as a guideline for preparation of a detail implementation schedule once the decision of the project execution is taken. Implementation period can be further shortened with careful detail planning and close monitoring of various activities involved in project execution.

The estimated capital cost of the project is Rs. 556.25 Crores inclusive of expenditure estimated for Pollution Control Measures as Rs.15 Cr. Detailed estimated breakup of project cost is given in Annexure-1

10.0 Environmental Management Plan

Air Environment

All major sources of air pollution (Cement Mill) will be provided with Bag houses & Bag filters to maintain emissions within the prescribed norms i.e. 30 mg/Nm3 for particulate matter emission from the stacks. Bag filters will be provided at all loading /unloading points and transfer points. Clinker will be stored in closed clinker silo; Gypsum is stored in covered shed and cement in Cement Silo. Fly ash will be stored in silos and closed shed. Proper maintenance of vehicles will be done to reduce gaseous emissions. Operators will be provided with personal protective equipment like safety Goggles, dust mask, ear plugs, helmets etc. Periphery of plant and surrounding areas of office building will be covered by thick green belt to attenuate the pollutants emitted by the Plant. Ambient air quality and stack emissions will be regularly monitored to keep emission levels below the prescribed limits .

Waste Water Generation & Treatment

No industrial waste water will be generated during process. Domestic waste water generated from the office toilets will be treated in the STP and treated water will be used for green belt development. Rain water harvesting will be practiced at plant.

Noise Environment

Walls and ceilings of the concerned buildings will be lined with sound absorbing materials. Properly insulated enclosures will be provided for high noise generating plant machinery. Personal Protective Equipment like earplugs and earmuffs will be provided to the workers.

Regular monitoring of noise level will be carried out and corrective measures in concerned.

Solid Waste Generation and Utilization

No solid waste will be generated from the cement manufacturing process. Dust collected from air pollution control equipment will be totally recycled in process. Sludge from Sewage Treatment Plant (STP) will be used as manure for green belt development. A part of used oil will be utilized for lubrication purpose & remaining will be sold to authorized members.

S.No. Waste Method of Disposal 1 Used Oil Used internally for lubrication of scraper chains 2 Used Grease Given to PCB approved agencies 3 Lead Acid Batteries Exchanging with PCB approved agencies and OEMs 4 Transformer Oil Given to PCB approved agencies

S.No. Types of Waste End Use/ Disposal 1 Dust collected from air Totally recycled in process pollution control equipment 2 Sludge is generated from Manure for green belt development sewage treatment plant 3 Solid waste generated from Disposed after segregating the waste into colony biodegradable and non-biodegradable

Greenbelt Development/Plantation

Out of total land i.e. 35 Acre of which 33% of the area will be developed as greenbelt area & plantation. A thick greenbelt all along the roads and plant will be developed.

Plantation will be done in and around the plant premises. 80% survival rate will be maintained with all possible efforts. The trees have been planted at suitable grid spacing to encourage proper growth. Local plant species have been preferred.

11.0 Conclusion

Proposed project will result in growth of the surrounding areas by increased direct and indirect employment opportunities in the region including ancillary development and supporting infrastructure. Special emphasis on financial and social benefits will be given to the local people including tribal population, if any, in the area. Development of social amenities will be in the form of medical facilities, education to underprivileged and creation of self-help groups. No adverse effect on environment is envisaged as proper mitigation measure will be taken up for the same.
